Meningiomas are not pituitary tumors.
Meningiomas and pituitary tumors are both intracranial tumors, but they are not subordinate and are different. Meningiomas are mainly intracranial tumors that occur in the meninges and interstitial tissues of the meninges, and can be manifested by headaches, seizures, sensory (vision, hearing, smell, etc.) abnormalities and impaired motor function.
Pituitary tumor is a group of tumors occurring in the anterior to posterior lobe of pituitary gland and epithelial remnant cells of craniopharyngiopharyngeal tube. In addition to the common symptoms of intracranial tumors such as headache, nausea, and vision loss, it can also have the manifestation of endocrine abnormality, and is related to the location of the pituitary tumors, for example, growth hormone tumors can have the manifestation of acromegaly.
It should be noted that some meningiomas are close to pituitary tumors (such as meningiomas of saddle node), which press on the pituitary gland and may cause endocrine function abnormalities. If the patient has any uncomfortable symptoms, he/she should go to the hospital, complete the examination, make a clear diagnosis, and get treatment as soon as possible.
